Description
XDA036 Power Amplifier 2*125W Board Power Amp Board UPC2581 With Power Tube A1943/C5200
Technical Parameters:
- Working voltage: AC-36V
- Output power: 2*125W (Class A and B)
- Magnification: 32 times
- Output impedance: 4-8Ω
- Harmonic distortion: <0.002%
- Product size: 168 x 85mm/6.6 x 3.3"
- Zero background noise
Quality Components:
- Transistor: 2SD669, A1930, C5171, A1943, C5200
- IC chip: UPC2581 (voltage amplification), UPC1237 (speaker protection)
- For Omron Relay: serves as speaker protection
- For NCC capacitors: for power supply filtering
- Capacitor decoupling for Siemens
- Japanese five-ring metal film resistors with an error of 1%
Module Design:
- High-speed diodes are used for power rectification, and audio capacitors for NCC are used for filtering
- Voltage amplifier adopts the HiFi-level dual-channel voltage amplifier chip UPC2581, which is an integrated circuit used by power amplifiers for Sony. UPC2581V pre-driver uses a low-distortion classic circuit, including a 2-channel input stage and a voltage amplifier stage, without a booster stage. Internal twin triodes have excellent consistency and obtain HiFi-level sound quality. The overlap of the external circuit of UPC2581V is also more flexible, giving designers more room to play
- Final current amplifier adopts A1943/C5200 or IRFP9240/IRFP240 paired transistors
- A potentiometer on the board to adjust quiescent current according to requirements
- Speaker protection circuit is played by the UPC1237 chip, and the relay for Omron protects speaker
Package Included:
- 1 x Power Amp Board
